Failure of a Prestressed Concrete Steel Strand
M - High Carbon SteelP - Wire RopeAp - StructureCd - Corrosion Fatigue
Cm - FeCl3+HCl+H2O Etched MicroDf - Bainite
The micrography of the pin far from the fracture surface shows a biphasic brass, and Pb inclusions that are intentional to give a free machining condition for the alloy.
